In Drupal6, I basically have a block (a hierarchical menu structure) that turns out like this in HTML: <div class="block block-menu_block" id="block-menu_block-1"> <div class="content"> <div class="menu-block-1 menu-name-menu-navigation parent-mlid-0 menu-level-1"> <ul class="menu"> <li class="leaf first menu-mlid-248 active active-trail"><a class="active-trail active" title="" href="/">Start</a></li> <li class="expanded menu-mlid-249 active"><a class="active" title="" href="/">Aktuell</a> <ul class="menu"> <li class="leaf first menu-mlid-259"> <a title="News und Presse" href="/news-und-presse">News and Press</a> </li>... What I would like to get is actually a lot simpler: <div id="topmenu"> <ul class="one"> <li>some main entry <ul> <li> some sub entry ... or maybe: <div id="topmenu"> <h2>some main entry</h2> <h3><a href="#">some sub entry</a></h3> <h3><a href="#">another sub entry</a></h3> <h2>another main entry</h2> So, keeping the structure, but being able to use simpler, even completely different tags, if and when needed. I think I understand from the drupal docs, that I am (maybe) looking at <div class="block block-menu_block" id="block-menu_block-1" ==> module := menu_block delta := 1 (?) regrettably, none of the suggested * block-[module]-[delta].tpl.php * block-[module].tpl.php * block-[region].tpl.php placed next to page.tpl.php has any impact (yes, I did clear the cache).
